Roll accommodation unit, processing apparatus, and roll setting method

A processing apparatus comprising:

• a roll accommodation unit that accommodates a roll of a continuous sheet such that the roll is rotatable about a horizontal axis;
• and
• a main body that pulls out the continuous sheet from the roll accommodation unit and performs processing on the continuous sheet,
• wherein the roll accommodation unit includes
• a roll support shaft to which the roll is attached,
• a pair of side walls that are disposed at an interval in a horizontal direction along the horizontal axis, and
• a pair of rolling bearings that are attached to each of the pair of side walls and are disposed at an interval in a width direction of the side walls,
• recessed portions with substantially V shapes along the width direction are formed at upper ends of the pair of side walls,
• the pairs of rolling bearings are attached to each of the side walls at positions corresponding to bottoms of the recessed portions such that the rolling bearings project upward beyond inclined surfaces of the recessed portions,
• the roll support shaft includes
• a support shaft main body that has a length corresponding to a distance between outer surfaces of the pair of side walls, and
• a pair of small-diameter portions that are provided at both ends of the support shaft main body and have smaller outer diameters than an outer diameter of the support shaft main body, and
• the roll support shaft is supported with the small-diameter portions abutting on outer circumferential surfaces of the pairs of rolling bearings in a state in which the support shaft main body is located at an interval from the recessed portions.
